NURSING BOTTLE AND NIPPLE.

SPECIFICATION forming part of Letters Patent No. 590,708, datedSeptember 28, 1897.

Application filed June 27,1896. Serial No. 597,1l2. (No model.)

To all whom it may concern.-

Be it known that I, HENRY MEIER, a citizen of the United States,residing at the city of New York, in the county and Stateof New York,have invented a certain new and useful Improvement Relating to NursingBottles and Nipples,of which the following is a specification, referencebeing had to the accompanying drawing, forming a part of the same.

IIeretofore the great difficulty in regard to nursing bottles andnipples has been that the nipple on account of the weight of the milk inthe bottle would detach itself therefrom, thereby allowing the milk tobe spilled. To overcome this difliculty and to produce a well-securednipple are the objects of this invention.

Referring to the drawing, the same represents a vertical central sectionof my invention.

To particularly describe my invention, I take the ordinarynursing-bottle provided with a thread a. c is a cap threaded to conformwith the thread on the bottle. The nipple g has two flanges h and i withan intervening groove between these flanges. The nipple is first appliedto the cap, so that its lower flange h will be within and its-upperflange i above said cap. The cap is then screwed down, so as to compressthe flange 71. against the mouth of the bottle The flange h makesthesecure joint, while the flange z'prevents milk from flowing into andcontaminating the joint between the cap and the nipple. It also servesto prevent the nipple from slipping through the cap when the same isdetached from the bottle, 7 g

It is hardly necessary to mention the ad vantages of this invention, butit will be seen that an air-tight joint will be formed between thebottle and the nipple and that it will be impossible for the nipple toslip or removeitself from the neck.

It will also be seen that the nipple and cap can be taken apart andcleaned.

For filling and cleaning the bottle the cap carrying the nipple issimply unfastened, rendering it needless to stretch and strain thenipple, as heretofore.

What I claim, and desire to secure by Letters Patent, is-

1. In a closure for bottles and the like, the combination of a nipplehaving two flanges at its lower portion of self-expanding material suchas rubber, a cap 0 entered into the space between the flanges of thenipple, the said cap 0 being of rigid material, all combined with abottle-neck, and means for securing the said rigid cap upon thebottleneck so as to compress the lower self-expanding flange of thenipple between the bottleneck and the rigid cap. 2. In a closure forbottles and the like, the

' combination of a nipple having two flanges at its lower portion ofself-expanding material such as rubber, a threaded cap a entered into 1the space between the flanges of the nipple,

the said threaded cap 0 being of rigid material, all combined with athreaded bottleneck, the said thread on the bottle-neck being engaged bythe thread on the rigid cap, whereby the rigid cap can be screwed downhard on the bottle-neck so as to compress the lowermost self-expandingflange between the top of the bottle-neck and the rigid cap.

3. A nipple for forming a bottle-closure comprising a nipple proper 9provided with a plurality of flanges at its lower portion, the saidflanges being of self-expanding material such as rubber and united by anintervening collapsible annular portion.
